It’s easy to assume that Jamie Dimon, the accomplished CEO of JPMorgan Chase, was simply stonewalling when he claimed that mounting trading losses in his bank were “blown out of proportion” — that he was unaware of how grave the situation really was.

Consider that after failing to notice losses that would eventually mount from $2 billion to $5 billion, Dimon reportedly confided to his wife that he had “missed something bad.”
